You can buy "single socket pins" or you can simply break them out
of a old pc cpu socket (you get a huge number ;-) ).
Remove the plastic completely and then use them.
to hold them straight insert a (junk) ic.
(there are also fake ics out of sheetmetal but i don't see the advantage.
you can of course lower the pins into the holes (big drill) so that they
are flush (or nearly)
with the surface. this is low profile and much better for HF i was told.
you can also buy suitable pins, without the narrow leg, that fit into big
enough holes
directly.
